Solution
The correct option is D Kinetochore and spindle fibres
The reason for chromosomal movement in anaphase is the kinetochore and spindle fibers. Anaphase is the stage of mitosis or meiosis when chromosomes split and the sister chromatids move to opposite poles of the cell. During anaphase II, the centromeres are split, and the new daughter chromosomes are pulled toward the poles. They take on a V-shape as they are pulled back. While the chromosomes are drawn to each side of the cell, the non-kinetochore spindle fibers push against each other, in a ratcheting action, that stretches the cell into an oval.So, the correct answer is option D.
